The only other copy of Action Comics #1 to receive such a high grade set a record when it sold for over $2 million in 2011, the eBay release said. The comic from the earlier sale "had cream to off-white pages, while the comic that will be available on eBay contains white pages and is in pristine condition," according to the announcement of August's auction.

"This is an extraordinary opportunity to acquire the most valuable comic book in existence and we look forward to sharing a piece of pop culture history with the global eBay community of 149 million buyers," Gene Cook, general manager of Emerging Verticals for eBay Marketplaces, said in the release.
